[SOLVED] "Mapping" an entire stage...?

This is possibly a silly question. Either because it's super easy or it's impossible -- I don't know which.

Is there any way to change the rotation of an entire stage, either locally or globally?

Basically, in one scene I have 7 movie player/projectors lined up next to each other and I would like to be able to map the whole stage to my projection surface so that I don't have to do each individual projector. (Because the show is on a mixed bill in a festival for which there is almost no tech time and so I'd like to be able to get the projection focused in as little time as possible). It's very straightforward -- center hung front projection -- and all I'd really need is the ability to do rotate and/or spin it?

I'm using the Stage Scaler actor to get very close to what I will need and now I just need minor tweaks.
